=218.= To the problem of the meaning and government of the universe three answers were current in the epoch with which we are dealing. Either all things take place by fate; or the world is ruled by a divine providence; or else fortune is supreme[1]. These three terms are not always mutually exclusive: Virgil speaks commonly of the ‘fates of the gods[2]’; and ‘fortune’ is frequently personified, not only in common speech, as when the Romans spoke of the ‘fortune of the city,’ but even by a philosopher like Lucretius, who speaks of ‘Fortune the pilot[3],’ with a half-humorous abandonment of exactitude. The Stoics have the merit of not only recognising fully these three powers, but also of using the terms with relative consistency. By fate then we mean an abstract necessity, an impersonal tendency, according to which events flow; by providence a personal will; by fortune the absence of both tendency and purpose, which results in a constant shifting to and fro, as when a man stands upon a ball, and is carried this way and that[4]. All explanations, both of general tendencies and of particular events, must ultimately resolve themselves into one or other of these three; every constructive system must necessarily aim at shewing that the three ultimately coincide, and that philosophy is the guardian and guide of mankind in the understanding of their relations one to another[5]. [Sidenote: Fate.] =219.= The Stoics hold that ‘all things happen by fate[6].’ To this conclusion they are brought by the same reasoning that moved the Chaldaeans. The visible universe is, and has motion. The heavenly bodies move incessantly in their orbits; there is no force either within or without them that can turn them aside a hair’s breadth, or make their pace quicker or slower. No prayers of men, no prerogatives of gods can make them change[7]. Without cause there is no effect; and each effect is in its turn a new cause. Thus is constructed an endless chain, in which all things living and inanimate are alike bound. If a man knew all the causes that exist, he could trace out all the consequences. What will be, will be; what will not be, cannot be. This first Stoic interpretation of the universe is that of Determinism; it reiterates and drives home the principle that is here our starting-point, ‘the universe is.’ ‘Chrysippus, Posidonius, and Zeno say that all things take place according to fate; and fate is the linked cause of things that are, or the system by which the universe is conducted[8].’ This ‘fate’ is only another name for ‘necessity[9]’; fates cannot be changed[10].
